I have a custom Sager gaming laptop with the following specs: i7-3630QM, GTX 680M, 32GB RAM. The laptop runs Witcher 3 smooth as pie when plugged into the AC adapter but when unplugged the game would run for 1 minute and shutdown the laptop completely. I have checked the power setting to make sure the laptop runs on full power when not plugged but it doesn't help. Any assistance on this would be great. Thanks in advance.
